How to Change AI Movement Speed with BEHAVIOUR TREE in the GAME ANIMATION SAMPLE | Unreal Engine 5

This video is a follow up to my last video (linked below) where I show you how to update the NPC Movement Speed using Behaviour Tree in the Game Animation Sample from Epic Games.

The Game Animation Sample doesn't come with any NPC characters, and we need to tweak a few things in order to get it to work with an AI Controller and Behaviour Tree. The Behaviour Tree I use in this video is very simple and is only intended to demonstrate how to get started setting up one of the characters so that you can take advantage of the Motion Matching animation blueprint with NPCs.

LEARNING PRE-REQUISITES: Basic knowledge of Behaviour Trees, Blueprint Interfaces, and Event Dispatchers.
